How many coats for good coverage?

On what surface did you paint? Have you ever calculated how much paint you needed per sqm?

Renovation fleece/ old coatings with partially problematic tones (light blue) as well as newly plastered electrical installations.

Finally, gray drywall on the attic.

Anywhere there were transitions (light/dark), we used primer.

We had calculated all areas beforehand and then estimated consumption at 6 sqm per liter + 10% reserve on top. For pre-mixed paints, if it was tight, we ordered the next larger bucket.

Actually, we had a good amount of all paints left over.

What I think was even more important was a proper set of rollers and brushes from the professional painter's supply store (no comparison with stuff from the hardware store), as well as sturdy roller frames made of aluminum.

And since we worked a lot with paint edges in the surfaces, the purple tape from Storch.

The Bosch PLL 360 was also helpful (best on a studio lamp stand) for taping off.

By the way, after almost 2 years we now had to renovate the roller shutter box in our kitchen. So in the end we also wallpapered it with new fleece and then skimmed it to the existing walls and then painted the area and the surroundings with the opened paint that was stored in the basement (it was still good in consistency).

No one can see that it had to be renovated there. Also, the white on white is not noticeable.

Partly drywall, partly plaster.

Masking tape, it does not have to be purple or blue on the inside, yellow is enough, since UV resistance on the inside is not important. Tesa, 3m, Storch, Kipp, whatever, they all can do it. It’s not rocket science. Primer paint, with white, the cheap sh... paint from the bottom of the shelf works very well for priming, as I said, it’s good for the undercoat, coverage and evenness come with the second coat on a branded basis. Please never forget to impregnate new walls with deep primer, here too the cheapest is enough, we filled it into a plant sprayer and sprayed all walls and ceilings, even drywall, after filling. This way the substrate no longer absorbed, and the paint finish is not blotchy but even. K.
